Question 1
What is the formula for the frequency of an RC phase shift oscillator?
- f_0 = RC
- f_0 = 1 / (2πRC sqrt(6))
- f_0 = 2πRC
💡 Hint: Look for a formula that includes both R and C values in its calculation.
Question 2
The gain condition for a three-section RC oscillator should be at least 29. Is this true or false?
- True
- False
💡 Hint: Consider why gain plays a crucial role in oscillation stability.
